Docker Outage History

A brief outage affected Docker Cloud and Testcontainers Cloud, causing temporary access issues for related features. The incident began at 3:20 PM UTC and was resolved by 3:30 PM UTC, lasting about 10 minutes. The Docker status page indicated both Testcontainers Cloud and Docker Cloud went down and later returned to full service. The provider issued two status updates during the incident, outlining the investigation and restoration steps. The impact appeared limited to these two components, with no broader disruption to other Docker services or regions.

On 3:40 PM UTC the Docker Hub status moved to warn as the Hub UI went down and authentication services were degraded. Access to the Docker Hub web UI and sign-in were impacted for about 15 minutes, with the issue resolved by 3:55 PM UTC. The incident affected Docker Hub Web Services and Docker Authentication.

The Docker status page posted two updates during the event, documenting the start and resolution. A small volume of user reports were observed, indicating UI access and login issues but no broader service impact beyond these components.

An incident affected Docker Cloud, with increased errors from Docker Offload causing slowdowns and intermittent connection issues for users. The issue began at 1:50 AM UTC and was resolved by 2:15 AM UTC, lasting 25 minutes. The Docker Cloud component transitioned from up to degraded and back to up, with two official status updates issued during the incident. The impact was limited to Docker Cloud; users may have experienced slower responses or difficulty connecting to Docker Offload features during the window.

During a scheduled back-end maintenance window, Docker Hub services including Docker Hub Registry, Docker Authentication, and Docker Hub Web Services were briefly disrupted. Users attempting signup, signup with social authentication, or provisioning new accounts could experience brief issues during the maintenance window. The maintenance began at 10:05 AM UTC and concluded by 11:05 AM UTC, lasting about 1 hour. The maintenance was aimed at back-end infrastructure upgrades and affected operations such as signup forms, signup with social auth, SSO provisioning for new users, SCIM creating new users, account deactivations, and create/delete repositories.

The Docker Hub Registry experienced degraded image pull performance beginning 3:35 PM UTC after monitoring detected issues tied to a third-party outage affecting the India region. Users pulling containers reported increased latency and, in some cases, failures. The issue appeared region-specific to India and persisted for nearly five days until 1:55 PM UTC when the status was updated to indicate recovery. The Docker status page issued two updates during the incident, first warning about the latency in India and later confirming that performance had returned to normal.

Docker Hub Registry experienced degraded performance for image pulls, with higher latency reported by users. The issue began on Jul 30, 2025 1:20 PM UTC and persisted until Jul 31, 2025 12:15 AM UTC, lasting roughly 10 hours and 55 minutes. The root cause was a third-party vendor outage affecting pull operations, with users in the India region affected.

Two official status updates were issued by Docker Hub Registry during the incident. The updates noted monitoring issues with pulls and later confirmed that the service had returned to normal. The impact appeared regionally concentrated in India, though latency may have affected other regions as well.

Docker Hub Registry experienced a brief degradation starting at 12:25 PM UTC, affecting repository management operations. Users could encounter failures when deleting repositories, modifying settings, or changing visibility. The incident lasted about 12:50 PM UTC (roughly 25 minutes) and was resolved by that time. The Docker status page posted two updates during the incident to explain the degraded state and the subsequent recovery, with impact focused on repository-management tasks rather than a global outage.

The issues appeared to be limited to repository deletion and related settings changes, according to the official updates.

An outage affected Docker services for about 10 minutes, beginning at 2:00 AM UTC when the Docker status page transitioned from up to down. The update carried the message 'test1' with details: 1, and the service was restored by 2:10 AM UTC.

Two official status updates were posted during the incident, documenting the outage and subsequent recovery, with the system returning to normal by 02:10 UTC.

During Jul 25, 2025 7:45 PM UTC to Jul 25, 2025 8:25 PM UTC, Docker reported delays in mirroring Docker Hardened Images, preventing customers from receiving new or customized images. This primarily affected workflows that rely on up-to-date hardened images and could slow deployments or security hardening tasks for about 40 minutes.

The Docker status page posted two updates during the incident, noting the delay and then the restoration of the image mirroring. The issue was resolved by Jul 25, 2025 8:25 PM UTC and affected a single component: Docker Hardened Images mirror.

An outage briefly affected Docker Desktop sign-in and the Docker Authentication service, preventing sign-ins and causing premature logouts for some users. The incident began at 3:10 PM UTC and involved two components: Docker Authentication and Docker Desktop. The Docker status page issued 2 updates as the issue was investigated, and services were restored by 3:55 PM UTC, for a total duration of 45 minutes.
